JOHN D. HENDERSON, OF HERKIMER, NEW YORK.

GAP-REMOVER.

Application filed November 20, 1911.

To all whom it may concern Be it known that I, J OHN D. HENDERSON, a citizen of the United States, residing at Herkimer, 'in the county of Herkimer and State of New York, have invented certain Improvements in Cap-Removers, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to devices for raising or removing the caps, covers or stops of bottles and jars, or other packages or containers, and is herein shown as embodied in a device which is especially adapted for removing the ordinary pasteboard caps or stops with which milk bottles are temporarily sealed. I

An object of the invention is to provide a device for this purpose which will be convenient to manipulate and which will remove the cap or stop without substantial injury thereto' and without danger of contaminating the contents of the container.

Another object of the invention is to pro and Fig. 3 shows a modified form of the invention.

In designing both the preferred form of the invention herein shown and the modified Specification of Letters Patent.

Patented Aug. 11?, 1915.

Serial No. 661,213.

from the plane of the body portion 2 in the opposlte direction, are fulcrum lugs 6 and 8. The lugs 6 and 8 are adapted to rest upon the surface of the cap when the point 1 has been forced beneath the surface and to serve as a fulcrum about which the point t turns as it raises or removes the cap. The curvature of the lugs 6 and 8 is preferably so related to the curvature of the point at as to facilitate forcing the point into the cap. The relative curvatures are such also as to produce the desired lifting effect when the device is turned about the lugs 6 and 8 as a fulcrum. F or convenience in hanging the device up when not in use, the body portion may be-provided with a hole 10.

In Fig. 2 is shown the manner of using the device. It will be apparent from an inspection of this figure that the width of the cap engaging end of the device should not be greater than the diameter of the cap 12 of the bottle 14, in order that the device may enter the depression in the head 16 of the bottle in which the cap is seated. If desired, however, the device may be wide enough at this end so that the outer edges of the lugs 6 and 8 will rest upon the cap over the seat in the head 16.

The modified form of the invention shown, in Fig. 3, difi'ers from the preferred form in that two points 18 and 20 are pro vided and that a single fulcrum lug 22 is located between these points.

From the foregoing description it will be noted that an important advantage of the cap remover herein described and illustrated is that it fulcrums upon the cap itself and operates first to raise one edge of the cap sufficiently to equalize the air pressure upon the two sides of the cap, after which the cap may easily be removed bodily. Another advantage obtained by the above-described construction and mode of operation of the cap remover of this invention is that by fulcruming the cap remover upon the cap and bending the cap about this fulcrum point or line to lift an edge to allow the air pressure to become equalized the necessity for piercing a holeentirely through the cap either for this purpose or to obtain the firm hold which is necessary when the cap is to be lifted bodily against the air pressure is avoided. The cap may thus be preserved for further use and the danger of contaminating the contents of the receptacle by contact with the cap remover or by matter forced into the receptacle in the cap piercing operation is eliminated.

It will be noted further that the cap remover is provided with a fulcrum edge of considerable lateral extent, an important advantage of this construction being that When the fulcrum edge bears upon the upper face of the cap a definite line of bend is determined for the operation of the cap remover as it lifts one edge of the cap by flexing the cap about this fulcrum edge. This threepoint engagement of the cap remover with the cap is also important in that it aids in directing the piercing point into the cap in such manner that said point will obtain a firm hold in the substance of the cap Without passing entirely through the cap.

Having described my invention, What I claim as new and desire to secure by Letters Patent of the United States is:

A cap remover comprising a body portion serving as a handle and lying substantially in one plane, a piercing point and a fulcrum, said point and said fulcrum being respectively oifset to opposite sides of the plane of said body portion and being constructed and arranged to provide a three-point engagement of the cap remover with the cap, said fulcrum being formed as an edge extending in a straight line across a substantial arc of the contour of said cap whereby in operation said edge divides said cap into two segments and provides a definite line of bend about which one of said segments is moved relatively to the other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN D. HENDERSON.
